Application filed August 3, 1912. Serial No. 713,181.

To all whom it may cone em Be it known that I, THOMAS TESDAL, a citizen of the United States, residing at Portprovide-means for propelling within thesame, and to provide means for supplying fresh air to the boat for the occupants thereof without the admission of water.

Another objectof the invention is to provide a life boat of the above character which will possessadvantages .inpoints of efficiency and durability, is inexpensive to manufacview 0 ture and at the same time is simple in construction and operation.

With the above and other objects in view,

the invention consists in the novel features Figure 1 is a side elevation of a life boat constructed in accordance with my invention. Fig. 2 is a top plan view. F1g. 3 is a sectional view taken on'the line 3-3 of Fig. 2. Fig. 4 is a sectional view taken on the lined- 4 of Fig. 1. Fig. 5 is a transverse sectional .view taken on the line 5--5 of --Fig. 1.v Fig. 6 is a detail perspective view of one end of one of the seats arran ed in the boat. Fig. 7 is a vertical se'ctiona view through one of the air inlets showing the operating means for opening and closing the same. Fig/8 is a top plan view of'one of the inlet openin Fig. 9 is a detail pprspective Fthe clamping means whic hold the doors of the oar openin in a closed osition. Fig. 10 is a si e elevation o the the boat is preferably formed in two sections, namely, the top or up or section 1 and the lower section 2 which is the hull of the boat. The upper and lower edges of the respective sections are connected together in any suitable manner and are adapted to have packed between them rubberor other water proof material so as toprevent Water, from entering the boat between the sections.

The hull of the boat is to be constructed of heavy steel plate with an exceptionally heavy bottom as'shown at 3 while the top section 1 will be of lighter steel plate so that in case of the boat rolling over in a severe storm, the heavy bottom will cause it to right itself again.

The hull of the boat is provided upon each side thereof with a plurality of openings 4 arranged adjacent the upper edge of the hull through which the oars are adapted to be inserted, these openings will be closed by means of the'swinging doors 5 when not,

in use so as to make .the hull water tight. The, doors 5 are held securely closed by means of the substantially U-shaped clamping members 5 the intermediate portions of which are threaded upon the inwardly ex.- tending rods 4 secured to the inner face of the doors 5. Thus it will be seen that when the doors areclosed, the clamping members will be swung transversely across the door and engage the hull of the boat to hold the doors in a closed position.'

Arranged within the hull of the boat are the seats 6 which are preferably of locker form so that the top which is hinged to the seat as shown at 7 may be raised whereby provisions "can be placed inthe locker for use in an emergency case. These seats which are of locker form are to be of suflicient size so as to hold about two weeks provisions for the occupants of the. boat. Secured to the seats are the bolts 8 which are adapted to encircle the waist of the persons seat by means of the strap 7 'The top portion 1 of the boat is provided with a centrally arranged hatch way 9 for enterin the same, said hatch way being closed y the swinging door 10 which is locked from the inside by means of the.

catch member 11. Each endof the top portion 1 is provided with the windows 12 which are of water tightconstruction so as to admit ,suflicient light to the interior of the boat. Extending upwardly from the top portion-1 are a plurality of air pipes 13 which allow the thorough circulation of air through the boat. In case the two should be overturned, these air pipes are-closed by means of the slidable valve members 14so as to prevent any water from entering into the interior of the boat. The valve members 14 are provided upon each side thereof with the outwardly extending lugs 14 which are adapted to be engaged by the slotted levers 23 mounted upon the shaft 25. In operating the shaft 25 to close the openings 2A in the pipes 13, a lever 22 is manipulated to rotate the shaft 25 and slide the-valve members 14 upon the guides 21 until they are arranged within the openings 24 to prevent water from entering the interior of the boat. These air pipes 13 may also be used for shooting sky rockets for signaling to attract the attention of passing vessels.

Arranged in the backof the boatis the water tank 15 which is tobe of suflicient size to contain a suficient supply of water for the, occupants of the boat. The rudder 16 is to be operated by means of the ropes 17 which extend from the rudder into the boat through the two rear oar openings 4 and are to be used in case the water is smooth enou h to allow of the propelling of the boat ymeans of the oars. In case the water is rough, the oar openings 4 will have to be.

closed by means of the door 5 to revent the entrance of water into the boat. s an extra precaution, the boat is to be equipped with the life belts 18 which are hung from the sides of thetop portion 1 where they may be easilyremoved and placed upon the occu ants of the boat. 1

rom the above description taken in connection with the accompanying drawings, it,

will be readily apparent that I have provided a simple and durable lite boat of the above character which can be manufactured at an extremely low cost and which may float upon any body of water no matter how rough it may be without injury to the occupants thereof. It will be apparentthat the boat may be used as an ordinary life boat by simply eliminating the top ortion 1, the life belts '18 which are genera ly-car-v ried by the top portion may be placed in the locker seats 6.

ile I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to forsuccessfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope of the appended claims.

Oar locks 4L are secured to the outer surface of the boat and preferably arranged in registration with the openings 4, said oar locks being adapted to support the oars when in use.

What I claim is 1 1 '1. Ina device of the character described, the combination of a sectional boat comprising an upper and lower section having their respective edges suitably connected together,

air inlet pipes arranged in the top section,

sliding valve member's adapted to close the inner ends :of said inlet pipes, said top sectionbeing provided with a hatch way, a swinging door adapted to close said hatch Way, a clamping member secured to the inner side of the door and adapted to hold the same in its closed position, said lower section being provided upon each side thereof with air openings, swinging doors adapted to close said openings and means for holding said doors in their closed position.

2. In a device of the character described,

the combination of upper and lower sections suitably connected together, said lower section comprising the hull constructed of metal plate and provided with an exceptionally heavy bottom, locker seats arranged transversely across the bottom of the lower section, said lower section being provided with oar openings upon each side thereof, swinging doors adapted to close said open ings, clamping members carried by the doors and adapted to be arranged transversely.

thereacross to holdthe doors in a closed position, air inlet pipes arranged in the top section, means for opening and closing said p'pes to admit air to the interior of the sections.

3. In a device of the character described, the combination of a'boat comprising upper and lower sections, means for forming water ti ht connections between said sections, air in ct pipes in the top section, guide rails arranged beneath said pipes, sliding valves mounted upon said rails and adapted to close the lowerendof said pipes, outwardly extending lugs formed upon each side of said valve member's, slotted levers having one end mounted uponsaid lugs, longitudinal shafts upon Wl'llCll the other end ofsaid levers are mounted, and operating means adapted to rotate said shafts to slide the valve members upon the guide rails and close the lower ends of the inlet pipes.

4i. In a device of the character described, the combination of a boat comprisingup'per and lower sections, .means for forming awater tight connection between said sections,

means for admitting air into the interior of the sections, said lower section being provlded with transversely extending seats,
